China Central Television, a
government-run TV station, recently reported that a McDonald’s restaurant and
a Carrefour store in China sold chicken products that were past their expiration dates.

According to McDonald’s food safety rules,
food that has not been sold 30 minutes after it was cooked should be thrown
away. However, the Chinese TV report said that a McDonald’s restaurant in Beijing
sold chicken wings that had been out for 90 minutes.

Employees at a Carrefour supermarket
in Zhengzhou, on the other hand, reportedly changed the expiration dates of some
raw chicken packs. They were also accused of changing product labels to sell regular chicken as
more expensive free-range chicken.

Both companies have posted apologies
to consumers on their Chinese websites. US-based McDonald’s said it will
seriously investigate what it
calls an isolated case. Paris-based
Carrefour said it will work with Chinese authorities to learn what happened
in the Zhengzhou store. The French chain also said it will make sure employees
undergo better training.

The reports add to the country’s growing
concern for food safety. China has already been dealing with a number of food
safety scandals including reports about deadly baby milk formula, pork containing
dangerous chemicals and re-used restaurant cooking oil.
